ROASTED ARTICHOKES WITH ANCHOVY MAYONNAISE

Steps:

• Prepare the artichokes: Fill a large bowl with cold water. Cut the lemon into quarters, and squeeze the juice from each quarter into the water. (This acidulated water will keep the artichokes from discoloring.)
• Snap off a few of the tough outer leaves (bracts) near the stem of each artichoke. Cut each artichoke in half from top to bottom, and lay the halves cut-side down on a cutting board.
• Using a sharp vegetable peeler and working one half at a time, trim the rough edges and the stems. Cut 1/4 inch from the bottom of the stem and 1/2 inch from the top of each half. Turn the halves over and use a teaspoon or melon baller to remove the hairy "choke." Place trimmed artichoke halves in the lemon water. Leave them in the lemon water until ready to cook.
• Heat oven to 425 degrees. Bring a large pot of well-salted water to a boil. Add drained artichoke halves and simmer for 10 minutes. Remove and place artichoke halves cut-side up in a stainless steel roasting pan or ceramic baking dish, in one layer.
• Tuck thyme sprigs under artichokes, and sprinkle artichokes with salt and pepper. Drizzle generously with olive oil, about 1 1/2 teaspoons per halved artichoke. Bake, uncovered and brushing with oil from the pan occasionally, until nicely browned, 30 to 40 minutes.
• As artichokes roast, make the anchovy mayonnaise: Put mayonnaise in a bowl and stir in chopped anchovies and capers, lemon zest and juice, garlic, cayenne and a little salt and pepper. Let sit for 5 minutes, then taste and adjust seasoning.
• When artichokes are ready, transfer to a serving platter or individual plates. Brush lightly with oil from the pan. Sprinkle with parsley and serve anchovy mayonnaise and lemon wedges, if you like, on the side.
